Arc'teryx Fit Guide

Trim Fit

Fits close to the body. These garments are patterned with lower volume for reduced bulk. Most compact, little room for layering.

Regular Fit

Allows for layering and freedom of movement. These garments use complex patterning and shaping to enhance motion and eliminate excess bulk.

Relaxed Fit

Has room for maximum winter layering. These garments rely on both articulation and higher volume patterns to provide comfort and mobility.

Arc'teryx Layering System

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.

The graph shows where this product sits within a layering system. Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
